Monitor is unique in controlling the troublesome weeds, Brome and Couch, in winter wheat throughout the growing season. And it goes further, killing Cleavers, Mayweed, Charlock and Volunteer Oilseed Rape.
Monitor also significantly stunts the growth of Volunteer Barley making it an invaluable tool for the seed wheat producer.
Monitor is taken up primarily through the leaves, via the cuticle with the assistance of the added surfactant. Once inside the tissue, sulfosulfuron binds to and inhibits a plant enzyme known as ALS, without which the plant cannot produce three essential amino acids for growth.
Symptoms of ALS inhibition include yellowing or purpling of leaves, stunting, then plant death. Weeds stop competing with the crop several hours after application, though it can take ten days for symptoms to start showing.
